Claims.

This invention relates to an improved tank or water closet. I

An object of this invention is to provide an improved water closet which includes an inner and outer receptacle spaced from each other and provided with an insulating material between the receptacles, there being means connected with the receptacles to permit ample ventilation of the insulating material and a cover of special construction to allow fresh air to enter the space between the receptacles.

Ancillary objects and features of importance will become apparent in following the description of the illustrated form of the invention.

In the drawings:

Figure 1 is a perspective view of the improved construction, the cover being removed and parts being broken away to illustrate internal detail;

Figure 2 is a fragmentary sectional view taken upon the line 2-2 of Figure 1 and in the direction of the arrows; and,

Figure 3 is a vertical sectional view taken substantially on the line 3-3 of Figure 1 but showing the cover in place.

The instant and illustrated device provides a tank which minimizes and in many instances completely prevents condensation on the outside of the water closet and avoids the necessity of trays for collection of such condensed moisture.

In the illustrated construction, there is an outer receptacle l0 provided with sides and a bottom wall l2. There are four sides 13, I4, I5, and IS. The outer receptacle I0 is made of stand ard material, as is the inner receptacle l8 which includes side walls 20, 2|, 22 and 23. There is a bottom wall 24 connected to the side walls of the inner receptacle and both of the receptacles are provided with open tops. The inner receptacle is made of such size as to provide an insulating chamber 26 between the walls thereof and the walls of the outer receptacle when the inner receptacle is located within the outer receptacle.

The tank illustrated in Figure 1 is provided with all of the standard equipment necessary; for example, the flush handle '28 which is arranged to be connected to standard flush mechanisms, a discharge pipe 30, together with unshown water inlet means.

Th chamber 26 has insulating material 32 of standard description, as rock wool, cork or others. In order to permit proper ventilation of the chamber 26 and the material 32 therein, a plurality of vertically disposed channels 34 are disposed in the chamber 26 and have a number of apertures 38 therein. At the four corners angles 40 are employed in lieu of channels, but the flanges of the angles 40 are provided with aper-' tures 42, as are the channels 34. I

Downwardly opening channels 46 are provided on the bottom wall l2 of the outer receptacle and constitute a seat for the inner receptacle l8. These channels which form air conductors or ducts are also apertured, as are the base channels 48 which are located at the junction of the side walls l3 and IS, with the bottom wall I2 of the outer receptacle. The last mentioned channels 48 constitute seats for the vertical channels 34.

A cover plate 50 having a plurality of apertures therein is disposed over the chamber 26, the vertical channels opening into the apertures therein.

The closure or cover 52 is preferably flat with a front depending flange 54 and a number of feet 56 adapted to rest upon the upper edges of the receptacles so as to space the cover 52 from the chamber 26 whereby proper circulation throughout the chamber 26 is permitted.

Having described the invention, claimed as new is:

l. A water closet tank comprising an inner receptacle and an outer receptacle, said receptacles being spaced from each other to thereby constitute an insulation chamber, a cover located on said receptacles, insulating material disposed in said chamber, a plurality of channels forming air conductors disposed in said chamber and opening upwardly, said air conductors being provided with a plurality of apertures to permit air circulation in said insulating material, and a cover plate disposed at the upper open end of said chamber and having apertures therein into which said conductors open, and spacing means between the bottoms of said receptacles for maintaining said receptacles in spaced relation to one another.

2. A water closet tank comprising an inner re-v ceptacle, an outer receptacle having said inner receptacle disposed therein, said inner receptacle being of such size as to have its walls spaced from the walls of said outer receptacle to thereby constitut an insulating chamber, insulating material disposed in said chamber, a plurality of vertically arranged channels constituting air ducts and having apertures therein, said channels being located in said chamber, bottom channels disposed in said chamber and having the first mentioned channels disposed thereon, and said bottom channels being apertured for air circulation.

3. A water closet tank comprising an inner receptacle, an outer receptacle having said inner receptacle disposed therein, said inner receptacle what is being of such size as to have its walls spaced from the walls of said outer receptacle to thereby constitute an insulating chamber, insulating material disposed in said chamber, a plurality of vertically arranged channels constituting air ducts and having apertures therein, said channels being located in said chamber, bottom channels disposed in said chamber and having the first mentioned channels, disposed thereon, .saidbottom channelsrbeing apertured for aircirculation,='; n
